arm: tegra13: add CPU and GPU EDP support

Incorporate new CPU leakage parameters and use T12x GPU leakage
parameters to enable VDD_CPU and VDD_GPU EDP dynamic limiting
based on temperature. EPD table is calculated done based on IDDQ
of CPU and GPU and leakage parameters provided by Silicon
characterization process.
